Try again. First, draw a scatterplot of the data in order to visualize the relationship. Examine the data and the scatterplot to determine if a linear model is appropriate. In order to determine if a linear model is appropriate, check the Quantitative Variables Condition, the Linearity Condition, the Equal Spread Condition, and the Outlier Condition. If a linear model is not appropriate, think about what can be done to improve the model
